The national average fell 2.3 cents per gallon in the last week to $3.65/g.

"The national average has started a nice downward trend, even as motorists were hitting the road for July 4," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "Yes, gas prices were some of the highest July 4 prices we've seen since 2008, they drifted downward in many communities as the holiday approached. Over the last week, the national average has fallen almost 4c/gal- a trend that could continue with an absence of hurricanes or disruptions from Iraq. Gas prices over the next few weeks could fall more than 10c/gal should the aforementioned situations remain quiet, which is most welcome as the peak of the summer driving season comes into focus," DeHaan said.

Amarillo gas prices are now 15.5 cents per gallon higher than the same day one year ago and 1.4 cents per gallon higher than a month ago.

The national average has decreased 0.7 cents per gallon during the last month but stands 17.5 cents per gallon higher than this day one year ago.
